documentation for tidy function needs updating

[doliv071]

Feature

The documentation for tidy states that ... are not used:

Additional arguments. Not used. Needed to match generic signature only. 

However, some specific tidy functions do use these dots e.g. tidy.glht which passes the dots to the summary function.
